Meseta Central,great interior meseta (plateau(meseta) of the Iberian Peninsula, central Spain. With Madrid at its centre, it extends over 81,000 square miles (210,000 square km) and has an average elevation of 2,300 165 feet (700 m660 metres). It constitutes the oldest and most complex geologic formation of the peninsula. Its western slope is gently inclined toward the Atlantic Ocean and forms the river basins of the DouroDuero, Tagus, and Guadiana . The other borders rise rivers. To the north the plateau rises abruptly into the Cantabrian Mountains(north) and , and to the east it becomes a series of rangeson the east. A certain symmetry is provided by the tectonic troughs of the Ebro in the northeast and the Guadalquivir in the south, which are overlooked by various ranges on to the east and by the Sierra Morena on to the south. The Meseta Central is divided by the block mountains in the centre of the peninsula divide the Meseta Central into the northern high basin of Old Castile the northern Meseta (Castile-León) and the lower plateaus of New Castile the southern Meseta (Castile–La Mancha and Extremadurato the south).

There is also contrast are contrasts in vegetation and economy between the western outcrops of crystalline rocks with poor soils and the eastern plains of limestones and marls that form the major agricultural zones. The southeastern section of the Meseta Central is occupied by the region of La Mancha.
